ATTACHMENT FOR OVEN-DOORS.

SPECIFICATION forming part of Letters Patent No. 318,155, dated May 19,1885.

Application filed November 18, 1884. No model.)

To all whom it may concern.-

Be it known that 1, Isaac A. ABBOT, of Denver, in the county of Arapahoeand State of Colorado, have invented a new and Improved Attachment toOven-Doors, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a new and improved attachmentto oven-doors to permit watching the contents of the oven, and also forshowing the temperature in the oven.

The invention consists in the combination, with an oven-door having anopening, of a frame secured on the door and holding a pane of glass ormica, and of a thermometer hinged to the frame inside of the pane.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side view of an oven provided with my improved attachment.Fig. 2 is an outside view of the frame of the attachment. Fig. 3 is aninside View of the same. Fig. 4. is a sectional plan view of the doorand attachment.

The oven-door A is provided at its middle with an opening, B, along therim of which a metal frame, 0, is secured by screws or otherwise on theouter surface of the door, and in the said frame a pane, D, of glass,mica, or other analogous transparent material is held.

On one upright of the frame 0 a graduated thermometer-strip, E, ishinged, on which a thermometer-tube, F, is secured. Thethermometer-strip E is held parallel with the glass pane D by a spring,G, so that the thermometer can easily be seen through the pane D.

The frame 0 and pane D, being held securely 0 on the door, prevent theescape of heat and permit of watching the articles in the oven, and thethermometer shows the degrees of heat in the oven. The thermometer-stripis held in place by the spring G, and, as it is hinged, it can be swungback for cleaning it, &c.

The abovedescribed attachment can be applied on various kinds of stoveor oven doors.

I am aware that an oven-door has been provided with a pane of glass heldthereto by a frame bolted to the inside of the door and provided with avertical cross-piece. To the cross-piece adjacent to the pane athermometer wassecured by looped wires, and I do not claim any suchconstruction as of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination, with an oven-door, of 60 a thermometer hinged on thesame, substantially as herein shown and described.

2. The combination, with an oven-door having an opening, of a framesecured on the door and holding a pane of glass or mica, and 65 of athermometer hinged on the frame, substantially as herein shown anddescribed.

3. The combination, with an oven door having an opening, of a framesecured on the door and holding a pane of glass or mica, a thermometerhinged to the frame inside of the glass, and a spring for holding thethermometer parallel with the glass, substantially as herein shown anddescribed.
